About plastics; plates, sheets, film, foil and strip, of polymers of styrene, cellular

HS code 392111 covers cellular plastic products made from polymers of styrene. These materials are widely used in a variety of industries, from packaging and insulation to construction and automotive applications. As a versatile and cost-effective material, cellular styrene polymers play a crucial role in the global economy, providing essential components and solutions for a wide range of consumer and industrial needs.

Production process

The production of cellular styrene polymer products typically involves a process called 'foaming' or 'expansion'. This involves heating and expanding the polymer material, often with the addition of a blowing agent, to create a lightweight, porous structure. The resulting cellular plastic sheets, films, and other forms can then be further processed, shaped, and fabricated into a variety of end-use products.

Production inputs

The main inputs required for the production of HS code 392111 items include the base polymer (typically polystyrene), blowing agents, and various additives such as flame retardants or colorants. Specialized machinery, such as extruders, molds, and cutting equipment, are also essential for the manufacturing process. Additionally, energy sources, such as electricity or natural gas, are needed to power the production facilities.

Production outputs

The cellular styrene polymer products covered under HS code 392111 are used in a wide range of applications, including 392112 Plastics; plates, sheets, film, foil and strip, of polymers of styrene, non-cellular, 392190 Plastics; plates, sheets, film, foil and strip, of other plastics, n.e.c. in heading no. 3921, and 392510 Plastics; builders' ware, n.e.c. in heading no. 3925. These materials are particularly well-suited for insulation, packaging, and protective applications due to their lightweight, durable, and thermal-resistant properties.
